GENERAL DESCRIPTION  
The ADA4091-2 dual and ADA4091-4 quad are micropower,  
single-supply, 1.2 MHz bandwidth amplifiers featuring rail-to-  
rail inputs and outputs. They are guaranteed to operate from a  
+2.7 V to +30 V single supply as well as from 1.35 V to 15 V  
dual supplies.

The ADA4091 family features a unique input stage that allows  
the input voltage to exceed either supply safely without any phase  
reversal or latch-up; this is called overvoltage protection, or OVP.  
Applications for these amplifiers include portable telecom-  
munications equipment, power supply control and protection,  
and interface for transducers with wide output ranges. Sensors  
requiring a rail-to-rail input amplifier include Hall effect, piezo-  
electric, and resistive transducers.  
NOTES  
1. NC = NO CONNECT.  
2. IT IS RECOMMENDED TO CONNECT THE  
EXPOSED PAD TO V–.  
Figure 4. 16-Lead LFCSP (CP-16-17)  
The ADA4091-2 is available in 8-lead, plastic SOIC and 8-lead  
LFCSP packages. The ADA4091-4 is available in 14–lead TSSOP  
and 16-lead LFCSP surface-mount packages.  
The ability to swing rail-to-rail at both the input and output enables  
designers, for example, to build multistage filters in single-supply  
systems and to maintain high signal-to-noise ratios (SNR).  
Table 1. Low Power, 36 V Operational Amplifiers  
The ADA4091 family is specified over the extended industrial  
temperature range of −40°C to +125°C. The ADA4091 family is  
part of the growing selection of 36 V, low power op amps from  
Analog Devices, Inc., (see Table 1).
